"recognised by _ as _" or "recognised as _ by _"
I don't think it matters semantically.
The first sentence slightly emphasises the recognition by all programmers, whereas the second sentence slightly emphasises the fact that IEEE 754 is the standard.
Note: I would write "the/a de facto standard".
Prepositional phrases like the ones in your example are often interchangeable. Some orderings may have different implications (@Joachim is right that the phrase you put first receives a bit more emphasis), but grammatically both sentences are fine.
